> The second patch is an optimization which is fresher and less tested, so I'll
> give it some more soak time before nominating it for the 1.7 branch.
> [0] In addition to the examples in the commit message, I can e.g. also imagine

> [PATCH 1/2] EXA: Extend mixed pixmaps scheme to allow driver PrepareAccess hook to fail.
> [PATCH 2/2] EXA: Try to minimize UploadToScreen calls for mixed pixmaps.

If possible avoid cluttering up exa.c with large chunks of
implementation specific code.
